DESCRIPTION
The skid control ECU (brake actuator assembly) acquires steering angle sensor zero point every time the ignition switch is turned ON and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores the previous zero point.
If front wheel alignment or steering wheel position is adjusted without disconnecting the negative battery terminal, or if yaw rate and acceleration sensor zero point is not acquired after the adjustments have been completed, the skid control ECU (brake actuator assembly) detects the difference between the previous zero point and newly acquired zero point and outputs this DTC to indicate a poor adjustment.
The steering angle sensor zero point malfunction warning will be canceled by turning the ignition switch off.

Steering Angle Sensor Zero Point Malfunction |
The steering angle sensor zero point calibration position vastly differs from the recorded value. |
|
CAUTION / NOTICE / HINT
NOTICE:
When replacing the skid control ECU (brake actuator assembly), perform zero point
calibration and store system information (See page
).
PROCEDURE
1. |
PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR |
(a) Perform zero point calibration of the yaw rate and acceleration sensor (See
page
).
HINT:
|
2. |
PERFORM STEERING ANGLE SENSOR ZERO POINT CALIBRATION |
(a) Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.
(b) Check that the centered position of the steering wheel is correctly set while driving straight ahead.
HINT:
If front wheel alignment and steering position are adjusted as a result of abnormal centered position of the steering wheel, acquire the yaw rate and acceleration sensor zero point again after the adjustments are completed.
OK:
The centered position of the steering wheel is correctly set.

Vehicle Speed Signal Malfunction (B2282,B2283)
DESCRIPTION
DTC B2282 is stored when the vehicle speed signal sent by the combination meter
assembly via direct line and the vehicle speed signal sent via CAN communication
do not match.
DTC B2283 is stored when a malfunction in the vehicle speed sensor is detected.
HINT:
When the cable is d ...
